Title: Bonding conductive bumps to conductive elements of electronic circuits
IPC: H01L23/495
Filed: 1981-04-28
Abstract: Bonding of conductive bumps to conductive elements of an electronic circuit such as a semiconductor integrated circuit is accomplished by providing a substrate 11 having thereon a plurality of conductive bumps 15 arranged in a predetermined pattern, aligning the electronic circuit adjacent the substrate such that the conductive elements 40 contact the conductive bumps, bonding the bumps to the conductive elements, and separating the bumps and electronic circuit from the substrate. In this manner, a plurality of conductive bumps can be bonded to the conductive elements of an electronic circuit in one operation. This method avoids the need for costly and extensive masking of the minute conductive elements, conserves precious metals and provides means for fabricating conductive bumps having contoured surfaces. <IMAGE>

Title: An improved method of manufacturing cable
IPC: G02B6/44
Filed: 1981-06-29
Abstract: In the manufacture of an optical cable comprising helically wound flexible optical cable elements, a faulty optical cable element is replaced by a sound optical cable element in a single operation using a single machine. In the method the cable C is caused to travel in a rectilinear direction, in the direction of its length, and, at a position 14 fixed in space along the advancing cable, the faulty optical cable element is unwound and wound on a take-up reel 5, and at the same time, the sound flexible optical cable element is helically wound from a pay-off reel 10 on to the advancing cable at the fixed position in space, in such a way that the sound optical cable elements fills the helical space vacated by the faulty optical cable element. The method is also applicable to electric cables comprising a layer of bare or insulated electric conductors helically wound around the cable axis. <IMAGE>

Patent GB-2097048-A (GB)
Title: Security doors
IPC: E05B15/02
Filed: 1982-03-15
Abstract: A security door 1, adapted to close off a secure area 3, is pivotally supported to allow the door either to open inwards to, or outwards from, the area 3. Normally the door is arranged for inward opening, and closes against a strike assembly including a stop member 8 and a bar 7, both screwed to the fixed frame 5. If the normal inward opening path of the door should become blocked, access can still be gained to the area 3 from the outside by releasing the parts 7 and 8 from the frame and then opening the door outwards. However, even with the parts 7 and 8 removed the lock bolt 10 or 11 still engages in an aperture 13 in the fixed frame so access can be gained to the area in this way only by key-holders or equivalent authorised personnel. <IMAGE>

Patent GB-2108788-A (GB)
Title: Dynamic braking system
Inventor: MARKHAM JOHN DAVID
IPC: H02P3/12
Filed: 1982-10-25
Abstract: A dynamic braking system is provided for a D.C. traction motor which is driven from bridge rectifiers (1, 21) having freewheel diodes (9) to permit circulation of motor generated current. The system employs field reversal to ensure a generated (braking) current direction the same as for motoring and this facility permits injection current braking by phasing up the supply bridges when the motor is braking with full excitation. A brake resistance is in two parts (23, 25) one of which (25) forms an uncontrolled arm of the bridge (21), this part of the resistance being shunted by a thyristor (27). Part way through an injection braking process the supply bridge is phased down, the resistance bridge arm shorted out and the supply bridge phased up again. Lower losses and greater braking efficiency result. <IMAGE>

Title: Semiconductor memory device
Inventor: MCPARTLAND RICHARD JOSEPH
IPC: H01L27/10
Filed: 1983-01-25
Abstract: Semiconductor memory cell spacing in one transistor one capacitor memories can be reduced by using a highly doped capacitance enhancement layer (53) as the isolating element between adjacent charge storage regions (55, 56) of a pair of cells sharing a common field plate (58). This allows elimination of the field oxide normally used for this function. Elimination of the field oxide permits closer packing of the cells. <IMAGE>

Title: Target locating display
Inventor: GREGORIS LORIS GIAMPAOLO
IPC: F41G3/02
Filed: 1983-02-08
Abstract: A target locating display for use by a gunner situated remote from his commander indicates the direction of a target upon reception of a signal from the commander location which represents the direction of the target from the commander's sensor. The display provides a compass sector mark which alerts the gunner to point his weapon in that direction, and an aiming indicator which indicates on a pair of light emitting diodes (100, 101) whether the weapon is aimed to either side or at the target. The display can be located up to, for example 500 metres from the commander. The signal to the indicators (100, 101) is derived by adding at (79) a weapon direction signal from (81), a parallax correction from (89, 78) and a weapon bearing correction signal from (77, 78) allowing for the distance (B) between the gunner's weapon and the commander. <IMAGE>

Title: Umbrellas and a handle therefor
Inventor: LADELL JOHN MICHAEL
IPC: A45B9/02
Filed: 1983-12-13
Abstract: The handle has three distinct portions, portions, namely two end portions 10, 11 and a central portion 12 and an internal recess 13 in the handle extends from one end along a substantial part of the handle and receives the shaft 14 of the umbrella therein. The handle is contoured externally such that the end portion at the shaft- receiving end has the greatest width, tapering towards the central portion while the other end is lesser width but also tapers towards the central portion. Thus, when the umbrella is in use the portion of greatest width is at the top of the handle and thus prevents any tendency for the handle to slip downwards in the users hand even when wet. The handle is preferably made of a rubber compound of the type used for golf-club handles and the central portion is preferably ribbed to provide a secure grip. At the free end of the handle a disc 15 is provided advertising material or the owner's name. <IMAGE>

Title: Damped fuel injection nozzle for internal-combustion engines
Inventor: GIESS HELMUT
IPC: F02M61/08
Filed: 1984-03-30
Abstract: Fuel injection nozzle for internal- combustion engines, comprises a valve needle (18) opening outwards and a pressure space (40), limited by two annular shoulders of the valve needle (18) into which opens a fuel channel (30, 34) has a spring chamber (32) designed as a damping chamber into which the fuel can flow only via a throttle channel in valve 54 so as to act on the upstream end face of the valve needle (18) and delay the rate of opening. Valve 54 formed by a wall portion is deflected during the closing stroke to permit rapid closing. Alternatively a piston may be used (Figs. 6-8) to provide no notable resistance to the displacement of the fuel from the spring chamber (32). This arrangement for damping the opening movement of the valve needle (18) is simple and involves only slight wear and allows a conventional design of the valve needle (18) to be used. <IMAGE>
